I thought the extreme HDR look went out of fashion when it became too easy for phones to do, and was overused.

These pictures don't have bad HDR artifacts (EG haloing) but even a casual observer will notice they don't feel natural at all. It's a shame because the framing and colors of those pictures are really nice, but the contrast (both high and low freq) gives them a completely synthetic feel. I'm guessing the sky was swapped out with a very dramatic overcast version, which also adds to the uncanny valley effect.
